The Longmenshan Structural Belt on the eastern edge of the Tibetan Plateau experienced the impactful Mw 7.9 2008 Wenchuan earthquake， causing a 350 km surface rupture. Traditional models attribute this to the Beichuan and Pengguan faults， but our research reveals a complex fault system at the northern end， with inconsistencies in surface rupture， aftershock distribution， and focal mechanisms. We integrates shallow geology， active source seismic reflection， and magnetotelluric profiling to establish a deep structural model for the northern end of the Longmenshan Structural Belt. This area exhibits dominant reverse thrust nappe tectonics， and analyzing the tectonic evolution history provides insights into deformation propagation from the orogenic belt toward the Sichuan Basin. Focal mechanism analysis and relocated aftershock data reveals two distinct types of seismogenic structures in the northern end of the Longmenshan Structural Belt. In the middle to northern segments， the reverse fault type is attributed to reactivated pre-existing faults. Conversely， at the northern end， the strike-slip fault type originates from high-angle co-seismic rupture cutting through pre-existing reverse faults. This study enhances our understanding of fault complexity and seismic mechanisms in the northeastern Longmenshan Structural Belt， providing new insights into regional tectonics.

四川盆地奥陶系五峰组–志留系龙马溪组黄铁矿–有机聚合体(FPA-OMA)丰富,通过扫描电镜结合氩离子抛光技术观察FPA-OMA赋存特征并探讨其形成机制及油气地质意义。结果表明, FPA-OMA可以划分为2类4亚类,Ⅰ_(1)亚类和Ⅱ_1亚类FPA-OMA富有机孔,Ⅰ_(2)亚类和Ⅱ_2亚类FPA-OMA缺乏有机孔。OMA由疏松多孔的沉积有机质聚合体转化形成,FPA为深水陆棚环境水–沉积物界面生物诱导形成的自生矿物聚合体,二者形成时序为OMA→FPA。FPA-OMA类型由OMA疏松程度决定,孔隙稀疏的OMA有利于形成Ⅰ类FPA-OMA,孔隙密集的OMA有利于形成Ⅱ类FPA-OMA。FPA-OMA有机孔发育程度与围岩抗压实强度有关,刚性颗粒作骨架的页岩抵抗压实作用能力强而发育有机孔,塑性颗粒承担巨大上覆地层压力的页岩难以保存有机孔, FPA并不能保护有机孔。

Distribution, geochemistry and age of the Millennium eruptives of Changbaishan volcano, Northeast China - A review

Frontiers of Earth Science 2014年第2期8卷 216-230页

Large explosive volcanic eruptions generate extensive regional tephra deposits that provide favorable conditions for identifying the source of volcanoes, comparing the sedimentary strata of a region and determining their ages. The tephra layer, referred to as B- Tm, generated by the Millennium eruption of Chang- baishan volcano, is widely distributed in Northeast China, Japan, D.P.R. Korea, and the nearby coastal area of Russia. It forms part of the widespread northeast Asian strata and is significant for establishing an isochronal stratigraphic framework. However, research on the temporal characterization and stratigraphic correlation of associated strata using this tephra layer is mainly concentrated in and near Japan. In northeastern China, this tephra layer is seldom seen and its application in stratigraphic correlations is even rarer. More importantly, the determination of accurate ages for both distal and proximal tephras has been debated, leading to controversy in discussions of its environmental impacts. Stratigraphic records from both distal and proximal Changbaishan ash show that this eruption generally occurred between 1,012 and 1,004 cal yr BP. Geochemical comparison between Changbaishan ash and the Quaternary widespread ash around Japan illustrates that Changbaishan ash is a continuous composition from rhyolitic to trachytic and its ratio of FeOT to CaO is usually greater than 4, which can be used as a distinguishing identifier among worldwide contemporary eruptions.

作者： ZENG Rong , HE jinliang, ZHANG Bo and gao Yanqing (State Key Laboratory of Power Systems, Department of Electrical Engineering, Tsinghua University, Beijing 100084, China) State Key Laboratory of Power Systems Department of Electrical Engineering Tsinghua University Beijing 100084 China

A circuit model with lumped time-variable parameter is proposed to calculate the transient characteristic of grounding electrode under lightning current, which takes into consideration the dynamic and nonlinear effect of soil ionization around the grounding electrode. The ionization phenomena in the soil are simulated by means of time-variable parameters under appropriate conditions. The generated electromagnetic field in the air is analyzed by using electrical dipole theory and image theory when the lightning current flows into the grounding electrode. The influence of soil ionization on the electromagnetic field is investigated.
